Yeah, I'll never forget the difference in my system when we moved from a second floor apartment to a house where I have a dedicated listening room in the basement on a concrete slab. Night and day!!! In the apartment I had bass issues I couldn't overcome (short of using room treatments as u guys have rightly mentioned). In the basement, no bass issues whatsoever -- just well-balanced sound. As has been said on this site ad nauseum, the room is the most important and most-often-neglected part of any system. Kudos to @erik_squires for consistently pressing this point!!!
